HANGER FOR TROLLEY-WIRES.

Specification of Letters Patent.

Patented Dec. 3, 1912.

Application filed June 30, 1910. Serial No. 569,629.

To all whom it may concern:

Be it known that I, ORSON WV. BRENIZER, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and

tate of Pennsylvania, have invented certain new and useful Improvementsin Hangers for Trolley-Tires, of which the following is a specification.

This invention relates to hangers for the trolley-wires of overheadelectric railways.

The object of the invention is to provide a novel, simple and eflicientclamping device adapted to clamp the trolley-wire and suspend it inposition, and to this end the invention consists in the novelconstruction and combinations of parts which will be hereinafter fullydescribed and claimed.

in the drawings :Figure 1 is a plan view of my improved hanger appliedto a trolleywire. Fig. 2 is a side elevation thereof. Fig. 3 is alongitudinal, horizontal section, on line 33 of Fig. 2. Fig. 4 is atransverse, vertical section, on line 4-4 of Fig. 2. Fig. 5 is atransverse, vertical section, on line 55 of Fig. 2. p

In the drawings my improved hanger is shown applied to a portion of anoverhead trolleywire, and my improvedhanger in its preferred form is ofthe following construction :7, 7 are two longitudinal bars or ears onthe lower portions of which are formed oppositely-disposed jaws 8, 8 andon the upper portions of which are formed outwardly-extending,longitudinal ribs 9, 9. The jaws 8, 8 are made parallel to each otherand are adapted to embrace the trolley-wire 6, and the outer faces 10,10 of the bars or cars 7, 7 beneath the ribs 9, 9 converge from the endsof the ears toward the central portions thereof, as clearly shown inFig. 3 for a purpose hereinafter explained. The upper inner portions ofthe bars or ears 7, 7 engage and are fulcrumed on each other, as at 11,in a manner to permit the lower portions of the ears to move toward andfrom each other and permit the seating of the jaws 8, 8 against thesides of the wire 6. After the upper portions of the bars or ears 7, 7are engaged with each other, and the jaws 8, 8 are seated against thesides of the wire 6, the wire is held clamped between the jaws bysuitable end members 12, 12 which are Oshaped in cross-section and whichembrace the upper portions of the bars or cars 7, 7 and the ribs 9, 9formed thereon,

the inner faces 13, 13 of the free ends of the members 12, 12 engagingthe faces 10, 10 of the ears 7, 7.

Each C-shaped member 12 is constructed so that the free ends of theinner faces 13, 13 may be sprung apart a slight distance when forcedupon the bars or ears 7, 7, whereby the spring action of said membersagainst the outer faces 10, 10 of the ears will force the jaws 8, 8 intofirm engagement with the sides of the wire 6. The inner ends of theC-shaped members 12, 12 are provided with projecting arms 14, 14 whichextend substantially parallel to the bars or cars 7, 7, and are providedwith teeth 15 adapted to engage notches 16, 16 formed in the ribs 9, 9of the bars or ears 7, 7. When the C-shaped members 12, 12 are forcedupon the bars or ears 7, 7 in the position shown in the drawings, thearms 14, 14 of each member 12 are in the condition shown at the lefthand end of Figs. 1 and 3, and after the members 12, 12 have been forcedinto the positions shown, the arms 14, 14 are bent into the conditionshown in Figs. 1 and 3 to engage the teeth 15, 15 with notches 16, 16.

In assembling the parts, the bars or cars 7, 7 are first engaged witheach other and with the wire 6. This being done, the members 12, 12 areforced or driven endwise toward each other upon the bars or cars 7, 7,until they reach the positions shown in the drawings, whereupon the arms14, 14 of each member 12 are hammered toward each other to engage theteeth 15, 15 with the notches 16, 16.

The distance between. the outer faces 10, 10 of the bars or cars 7, 7 isslightly greater than the distance between the inner faces 13, 13 ofeach member 12 before the members 12, 12 are applied to the bars or cars7, 7; and the inner ends of the faces 13, 13 of each member 12 areflared outwardly, as at 12 to permit the application of the members 12,12 to the ends of the bars or cars 7, 7. It will thus be seen that whenthe members 12, 12 are forced upon the bars or cars 7, 7, as previouslyexplained, the faces 13, 13 of each member 12, will be forced a slightdistance apart thereby causing inward pres sure against the outer faces10, 10 of the bars or ears 7, 7. It will also be seen that when theparts are assembled, as previously described, the inwardly convergingfaces 10,

of the members 12, 12 working outwardly upon the bars or ears 7, 7.

When it is desired to remove the hanger from the trolley-wire, it ismerely necessary to bend the arms 14:, 14 outwardly to disengage theteeth 15, 15 from the notches 16, 16 and then force the members 12, 12from the ends of the bars or ears 7, 7 upon the jaws 8 and may be movedapart to free the wire.

One of the bars 7 is provided with a centrally-arranged,upwardly-extending boss 17, provided with a screw-threaded openingtherein into which is screwed the lower end of a screw-threaded rod 18by -means of which the hanger may be suspended from any suitablesupport, such, for example, as the supports usually carried by thecrosswires and provided with downwardly-extending screw-threaded rods,the rod 18 representing the rod of such support.

I claim 1. In a hanger for trolley wires, two clamping members providedon their lower portions with wire clamping jaws, suspending meansconnected to one of said members, said members having outer oppositefaces which converge from the outer ends of said members toward saidmeans, and a member engaging said faces and forcing said jaws towardeach other, one of said members being resilient and pressing said jawstoward each other.

2. In a hanger for trolley wires, two

clamping members provided on their upper portions with outwardlyextending, longitudinal ribs and on their lower portions with wireclamping jaws, suspending means connected to one of said members, saidmembers having outer opposite faces which converge from the outer endsof said members toward said means beneath said ribs, and a memberC-shaped in cross section embracing said ribs and engaging said facesand forcing said jaws toward each other, one of said members beingresilient and pressing said jaws toward each other. 7

3. In a hanger for trolley wires, two clamping members provided on theirlower portions with wire clamping jaws and provided also with notches,suspending means connected to one of said members, said members havingouter opposite faces which converge from the outer ends of said memberstoward said means, a member engaging said faces and forcing said jawstoward each other, one of said members being resilient and pressing saidjaws toward each other, and arms projecting from said member andprovided with projecting teeth, said arms being bent and said teethbeing engaged with said notches.

In testimony whereof I affix my signature in the presence of twowitnesses.
